Have recently mounted Nuteck airless on my main ride. Over 200 miles this week. I like them though they're slower than pneumatics, no doubt. 2 hr rides are 2.25 hr rides, etc. They feel different, but not so much as to make a huge deal out of it. I'm sure the MP is a great tire and very flat resistant. But, if you want to be completely free of the possibility of a flat the airless option is the only way to go. I'm anxious to try them in wet weather. It's been unusually dry here in mid-Tn this spring, so there's been no opportunity. Tons of discourse about the merits or lack thereof re the airless option w/bike guru Sheldon Brown being firmly in the anti-airless camp. If you decide to try them make sure you get ones rated 20 psi above where you normally run your pneumatics and oversized a little. Put 'Nuteck tires' into the commuter search option for more info.
